Hi Michael,
I am in fact using ASUS drivers, the latest version downloaded from the web. In fact, after uninstalling ALL the video drivers I got to boot from windows.. but I get a 640x480 resolution from the default VGA driver.. The device manager shows the Intel HD Graphics 4000 with the following error: "The device cannot find enough free resources that it can use. (Code 12). If you want to use this device, you will need to disable one of the other devices on this system."
I haven't been able to get through this error.
